Service Monitor host. You can change this by modifying the Service Monitor Storage
Directory configuration (

- Time-series metrics and health data - Time-Series Storage

- YARN application metadata - YARN Storage (
firehose_yarn_storage_bytes- 1 GB default)
For information about how metric data is stored in Cloudera Manager and how storage limits impact data retention, see Data Granularity and Time-Series Metric Data.
The default values are small, so you should examine disk usage after several days of activity to determine how much space is needed.
